Bottom Sediment Granulometric Data for the Continental Margins of the Bering, Chukchi,
East Siberia, Laptev, and Beaufort Seas

sample locations in study area

These data are part of Roberts, Richard W., University of Washington, Department of
Oceanography Special Report No. 70, Bottom Sediment Granulometric Data for the Continental
Margins of the Bering, Chukchi, East Siberian, Laptev, and Beaufort Seas. The report
was funded by Grant OCE76-20834, from the National Science Foundation, with additional
support from the Office of Naval Research, the US Atomic Energy Commission, and the
US Geological Survey. Data in the report represent granulometric analyses conducted
by UW of over 4,300 sediment samples from approximately 1,500 stations collected during
cruises of the Brown Bear, Thomas G. Thompson, Northwind, Staten Island, Burton Island,
Surveyor, John N. Cobb, and Drifting Ice Station Alpha II. The full report accompanying
the tabular data is available in .pdf form online (27.4 Mbytes).Data include collecting
institution, ship, cruise, sample id, latitude/longitude, date of collection, water
depth, sampling device, method of analysis, sample weight, sampled interval, raw weight
percentages of sediment, within a given phi range. Some samples also have percentages
of total gravel, sand, silt, clay, and statistical measurements such as mean, median,
skewness, kurtosis, and standard deviation of grain size. These data are part of the
larger NGDC digital grain size database.

While every effort has been made to ensure that these data are accurate and reliable
within the limits of the current state of the art, NOAA cannot assume liability for
any damages caused by any errors or omissions in the data, nor as a result of the
failure of the data to function on a particular system. NOAA makes no warranty, expressed
